摘　　要：从变形机翼的发展历程出发,综述了变形机翼的变形方式,主要包括面内变形(变展长、变弦长、变后掠)、面外变形(展向弯曲、变上反角、机翼扭转、机翼折叠)、翼型变形(变弯度、变厚度)以及组合变形。详细阐述了各种变形方式对飞行器飞行性能的影响,重点介绍了当前变形机翼各种变形方式的研究现状,指出为满足复杂严酷飞行环境、多飞行状态和多任务需求,变形机翼正在朝智能实时环境感知、主动变形、智能柔性变形和多种变形组合的方向发展。Starting from the development history of the morphing wing, the morphing modes, including planform alteration(variable span, variable chord, variable sweep), out-of-plane transformation(span-wise bending, variable dihedral, wing twisting), airfoil adjustment(folding wing, variable camber, variable thickness)and combined morphing were introduced. The effects of various morphing modes on the flight performance of the vehicle were elaborated in detail, and the current research status of various morphing modes of the morphing wing was emphasized. To meet the requirements of complex and harsh flight environment,multi-flight states and diversification of flight missions, the morphing vehicle can sense the external environment in real time and change its geometrical shape actively to adapt itself to ensure excellent flight performance. The intelligent flexible deformation and a variety of deformations combination are the developing trends.
